Function appendIsraelAndTracking

appendIsraelAndTracking(
    url: string,
    il: boolean,
    utmSource?: string,
    utmMedium?: string,
    utmCampaign?: string,
): string
Adjusts a Hebcal.com event link for Israel/Diaspora and appends UTM tracking parameters. For www.hebcal.com holiday/sedrot/omer links, this also sets i=on when il is true, rewrites the host to the shorter hebcal.com and shortens the path (see shortenSedrotUrl() for sedrot), and uses the abbreviated us/um/uc parameter names instead of the full utm_source/utm_medium/utm_campaign (the us/um params are omitted when utmCampaign starts with 'ical-' or 'pdf-', since those campaigns are tracked by uc alone). For all other URLs, the standard utm_source/utm_medium/utm_campaign parameters are appended, and utm_source defaults to 'hebcal.com' when not otherwise specified.
Parameters
- url: string
  the event URL to rewrite
- il: boolean
  true to mark the link as using the Israel holiday schedule
- OptionalutmSource: string
  tracking source, e.g. 'js'
- OptionalutmMedium: string
  tracking medium, e.g. 'api'
- OptionalutmCampaign: string
  tracking campaign, e.g. 'ical-foo'
Returns string
the rewritten URL as a string
